Tuple Data Type in Python

What is Tuple Data Type?

Tuple is special type of data structure in Python which is immutable. Immutable means once you create tuple data type you cannot add, modify or delete tuple data items. The tuple data items are enclosed within pair of parenthesis and separated with comma.

·        Tuple is an ordered, immutable collection of elements

·        which can be of different types

·        represented in pair of parenthesis and separated with comma

·        immutable means once tuple is created its contents cannot be changed

·        list is mutable means list items can be inserted. modify or deleted

·        tuples are immutable means you cannot insert or modify or delete tuple items once it is created

How to Create Tuple:

tuple1=(1,2,3)

print(tuple1)

Output:

(1, 2, 3)

 

Another Example,

tuple2=(1,0,10.5,"hello")

print(tuple2)

Output:

(1, 0, 10.5, 'hello')

Methods of Tuple:

1.      Count():

Count function returns the number of occurrences of a specified element in a tuple.

Example,

my_tuple=(1,2,3,4,5,4,5,4,5,4,5,5)

print(my_tuple.count(5))

Output:

5

2.     Index():

Index method returns the index of first occurrence of a specified element from tuple.

Example,

tuple1=(1,2,3,3,4,5,6,7,8,9)

print(tuple1.index(3))

 

Output:

2

3.     Len():

Len() returns numbers elements in a tuple

Example,

my_tuple=(1,2,3,4,5,6,7,8,9)

print(len(my_tuple))

Output:

9

4.     Sorted():

The sorted() returns the new tuple containing the sorted element of original tuple.

Example,

my_tuple=(1,22,33,4,5,6,0)

sorted_tuple=sorted(my_tuple)

print(my_tuple)

print(sorted_tuple)

Output:

(1, 22, 33, 4, 5, 6, 0)

[0, 1, 4, 5, 6, 22, 33]

Sorted() returns the new tuple and cannot modify original tuple

my_tuple=(1,22,33,4,5,6,0)

sorted_tuple=sorted(my_tuple,reverse=True) #reverse=True for descending order

print(my_tuple)

print(sorted_tuple)

Output:

(1, 22, 33, 4, 5, 6, 0)

[33, 22, 6, 5, 4, 1, 0]

 

5.     Max():

The max() returns the maximum value in the tuple

Example,

my_tuple=(1,2,3,4,5,6,20,50)

print(max(my_tuple))

Output:

50

6.     Min():

The min() returns the minimum value from tuple

Example,

my_tuple=(1,2,3,4,5,56,0)

print(min(my_tuple))

Output:

0
